Spin- and Angle-resolved Photoelectron Spectroscopy Study of the Quantum Spin Hall Insulator Bismuthene and its Precursor Phase

Niclas Tilgner, Andres David Peña Unigarro, Susanne Wolff +6

Recent studies have revealed that a confined bismuth layer at the graphene/SiC interface can be reversibly switched between a topologically trivial precursor phase and the quantum…

p-Wave Orbital Angular Momentum Texture in a Chiral Crystal

Dongjin Oh, Chiara Pacella, Xiangyu Luo +8

The spin and orbital angular momentum (SAM and OAM) are conceptually analogous, yet their roles in condensed matter systems have not been often treated on equal footing. While SAM…

Disentangling bulk and surface electronic structure using targeted cleave planes in RuO

Maria H. Visscher, Sebastian Buchberger, Bruno Saika +6

Rutile RuO has attracted significant interest due to its putative unconventional electronic and magnetic properties and its proximity to superconductivity. However, the measure…

Discerning ground state and photoemission-induced spin textures in altermagnetic -MnTe

D. A. Usanov, S. W. D'Souza, A. Dal Din +12

The recently discovered class of altermagnets provide a physical realization of an unconventional compensated magnetic phase with a higher partial-wave type of ordering, reminiscen…

Unconventional relativistic spin polarization of electronic bands in an altermagnet

A. Dal Din, D. A. Usanov, L. Å mejkal +22

Altermagnetism is a recently identified phase with a d, g or i-wave spin symmetry of magnetic ordering. Its discovery opens new research fronts at intersections of magnetism and sp…

Hund flat band in a frustrated spinel oxide

Dongjin Oh, Alexander Hampel, Joshua P. Wakefield +26

Electronic flat bands associated with quenched kinetic energy and heavy electron mass have attracted great interest for promoting strong electronic correlations and emergent phenom…
